Last updated 27 October 2026.
Kilulu is a language app for children, set up and managed by a parent or guardian. We collect only what the app needs to work, we never sell or share it for advertising, and there are no ads, analytics or trackers in the app or on this site.
What we keep, and why
- Your account. The parent's email address (or the private address Sign in with Apple gives us), so you can sign in and your family is saved across your devices.
- Your children's profiles. Each child's first name or nickname, their level (little or big learner) and the cat they picked, so the same profiles appear on each of your devices.
- Learning progress. Which lessons each child finished and which stickers they earned, with the time, so progress follows them between devices and you can see their week.
- Family voices. If you invite relatives to record words, we keep the name you give each relative and their recordings. Recordings are private to your family and only play to your children after you approve them.
- The waitlist. If you join it on this site, your email address and whether you use iPhone or Android, only to tell you when Kilulu is available.
What never leaves your device
- Your child's voice. When a lesson asks them to say a word, the recording is played back to them and then deleted when the lesson ends. It is never uploaded.
- Photos, contacts, location and dates of birth: Kilulu doesn't ask for them.
- Your settings, such as sound effects, captions and the optional daily reminder.
Children
Children use Kilulu inside profiles a parent creates. Children can't create accounts, buy anything, follow links out of the app or change settings: those are behind a grown-up check. We don't knowingly collect anything from children beyond the profile and progress described above.
Who handles it for us
- Supabase hosts our database, sign-in and file storage, and sends sign-in codes by email. It processes data only to run Kilulu for us.
- Apple handles subscriptions and payments. We never see your payment details; Apple tells the app only whether a subscription is active.
The voice that reads Kilulu's instructions is recorded ahead of time. Nothing about your family is sent to make it.
Keeping and deleting it
We keep your family's data while your account exists. In the app, Settings → Delete all data permanently deletes your account, profiles, progress and family recordings from our servers and from the device. Signing out removes them from that device only. You can also export a copy from Settings, or email hello@kiluluapp.com to have anything corrected or deleted, or to leave the waitlist.
Changes
If we change what we collect, we'll update this page and its date, and tell you in the app before anything new is collected.
